Symptoms of vertebrobasilar artery spasm are vertigo, impaired consciousness, motor dysfunction, and sensory impairment. 1. Vertigo: The most common clinical symptom of vertebrobasilar spasm is vertigo. Patients often describe it as a sense of rotation, mostly accompanied by nausea, vomiting, panic, sweating, constipation and other autonomic symptoms, and some patients may also be accompanied by tinnitus, hearing loss, unsteady walking, blurred vision and other symptoms. 2. Consciousness disorder: spasm of vertebral basilar artery can also lead to transient consciousness disorder, which is mainly caused by ischemia of brainstem reticular formation. 3. Motor dysfunction: Damage to the vestibulospinal tract may cause limb weakness of the upper and lower limbs, both lower limbs, three limbs and four limbs, which may be manifested as weakness of the limbs crossed on both sides, paralysis, and inflexibility of the arms and legs. Cerebellar dysfunction may appear ataxia. 4. Sensory disorders: sensory loss, numbness, sensory abnormality in limbs or parts of limbs and face. When the symptoms of vertebral basilar artery spasm appear, it is recommended that patients go to the Neurology Department of regular hospitals in a timely manner to improve the relevant auxiliary examinations under the guidance of professional physicians to clarify the cause of the disease and standardize the treatment, so as to avoid delaying the condition.
